Unable to add your boarding passes to apple wallet. Please try again later. How to fix this??

Both my husband and I are unable to add boarding passes to Apple Wallet. We were both able to in August and now we are both unable to. We get a pop-up that says “unable to add your boarding passes to apple wallet. Please try again later.” We’ve both tried numerous times, have both rebooted our phones and ensured we have the most updated IOS to no avail.

Anyone else experience this recently and figure out how to get it to work?
